CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 398,500, dated February 26, 1389.

Application filed September 27, 1888. Serial No. 286,479. (No model.)

To all whom it may concern:

Be it known that I, IRA CALAWAY DoYAL, a citizen of the United States, residing at Chumley, in the county of De Kalb and State of Alabama, have invented a new and useful Iinprovenient in Oar-Couplings, of which the following is a specification.

The invention relates to improvements in car-couplers; and it consists in the construction and novel combination of parts hereinafter described, illustrated in the drawings, and pointed out in the claims hereto appended.

In the accompanying drawings, Figure l is a perspective view of a car-coupling embodying the invention. Fig. 2 is a central vertical longitudinal section of the saine.

The invention is not a twin coupler, as the mechanism at each end of the car varies in That which is common to both ends will be described first.

A designates the end of a ear, and B designates a draw-head attached thereto and provided with a recess and` an upper and lower pin-opening, so that it can be coupled by an ordinary link and pin, if necessary. The upper edge of the front of the draw-head is inclined upward at a, as shown, for the purpose ofdirecting the end of the link C upward.

D is a block secured to the upper surface ot the draw-head, ruiming longitudinally thereon, having` its face d inclined upward and inward, and having the shoulder d projecting inward from its top, whereby the link C will be prevented from rising over the block D and the cars becoming uncoupled. At one end of the cara spring, E, is attached in such manner that its free end bears upon the top of the adjacentblock D. To the opposite end oi the car a transverse shaft, F, is journaled, a suitable distance above the corresponding block D, and provided at its ends with the crankarms ff, which stand on the outer sides of the car, so that the shaft can be turned without the brakenian going between cars G is a drum, secured centrally on the shaft F, and g is a chain having its upper end attached by means of a staple, or otherwise, thereto. The lower end of said chain is secured to the center of a second chain, I-I, the

under the shoulder d of the corresponding block.

I is a detent-bar passing through a guidestaple, e', secured to the upper surface of the.v

draw-head, and with its outer end rest-in g upon the adjacent end of the link, to prevent the outer end thereoic from falling too far down to couple readily.

It is evident that when two cars come together the outer end ot the link will ride up on the inclined face d of the opposite block D, under the end of the spring E, and will fall below the should er d ot said block. The cars will thus be coupled, and the spring will prevent the link from being accidentally detached from the block D.

The brakeinan uneouples the cars by winding the chain g on the druin G, thereby raising the outer end vof the link into position to disengage from the opposite block D.

Having described my invention, I claim l. In a car-coupler, the combination, with the link of the blocks secured to the drawheads and having inclined faces and provided with shoulders standing inward an dover the ends of the link, of the transverse shaft journaled on one end of the car and havingl crank-arms, the druln secured to said shaft, and the chains secured to the drum and to the sides of the link, and operating substantially as and for the purpose described.

2. In a car-couplcr, the combination, with the link C and the block D, secured to the draw-head an d having the inwardly-standin shoulder d', of the detent- -bar I, passing through the guide-staple `"and resting upon the adjacent. end ot' the link, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
